Abstract (en)
[origin: EP2907611A1] The object is to provide a method for manufacturing a heat exchanger plate capable of easily performing friction stir welding at a deep position of the heat exchanger plate, and capable of improving air-tightness and water-tightness. The method includes a lid groove closing process to insert a lid plate (5) into a lid groove (4) formed at a periphery of a concave groove (3) opening to a surface (2a) of a base member (2) ; and a primary joining process to perform friction stirring while relatively moving a primary joining rotary tool equipped with a stirring pin (F2) along a butting portion (J) of a side wall of the lid groove (4) and a side surface of the lid plate (5), and in the primary joining process, the rotating stirring pin (F2) is inserted into the butting portion (J), and the friction stirring is performed in a state of only the stirring pin (F2) being in contact with the base member (2) and the lid plate (5).
